Mem0 now supports **Graph Memory**.
With Graph Memory, users can now create and utilize complex relationships between pieces of information, allowing for more nuanced and context-aware responses. 
This integration enables users to leverage the strengths of both vector-based and graph-based approaches, resulting in more accurate and comprehensive information retrieval and generation.

<Note>
NodeSDK now supports Graph Memory. 🎉
</Note>

## Installation

To use Mem0 with Graph Memory support, install it using pip:

<CodeGroup>
```bash Python
pip install "mem0ai[graph]"
```

```bash TypeScript
npm install mem0ai
```
</CodeGroup>

This command installs Mem0 along with the necessary dependencies for graph functionality.

Try Graph Memory on Google Colab.

## Initialize Graph Memory

To initialize Graph Memory you'll need to set up your configuration with graph
store providers. Currently, we support [Neo4j](#initialize-neo4j) and
[Memgraph](#initialize-memgraph) as graph store providers. 


### Initialize Neo4j

You can setup [Neo4j](https://neo4j.com/) locally or use the hosted [Neo4j AuraDB](https://neo4j.com/product/auradb/).

<Note>If you are using Neo4j locally, then you need to install [APOC plugins](https://neo4j.com/labs/apoc/4.1/installation/).</Note>

User can also customize the LLM for Graph Memory from the [Supported LLM list](https://docs.mem0.ai/components/llms/overview) with three levels of configuration:

1. **Main Configuration**: If `llm` is set in the main config, it will be used for all graph operations.
2. **Graph Store Configuration**: If `llm` is set in the graph_store config, it will override the main config `llm` and be used specifically for graph operations.
3. **Default Configuration**: If no custom LLM is set, the default LLM (`gpt-4o-2024-08-06`) will be used for all graph operations.

Here's how you can do it:


<CodeGroup>
```python Python
from mem0 import Memory

config = {
    "graph_store": {
        "provider": "neo4j",
        "config": {
            "url": "neo4j+s://xxx",
            "username": "neo4j",
            "password": "xxx"
        }
    }
}

m = Memory.from_config(config_dict=config)
```

```typescript TypeScript
import { Memory } from "mem0ai/oss";

const config = {
    enableGraph: true,
    graphStore: {
        provider: "neo4j",
        config: {
            url: "neo4j+s://xxx",
            username: "neo4j",
            password: "xxx",
        }
    }
}

const memory = new Memory(config);
```

```python Python (Advanced)
config = {
    "llm": {
        "provider": "openai",
        "config": {
            "model": "gpt-4o",
            "temperature": 0.2,
            "max_tokens": 2000,
        }
    },
    "graph_store": {
        "provider": "neo4j",
        "config": {
            "url": "neo4j+s://xxx",
            "username": "neo4j",
            "password": "xxx"
        },
        "llm" : {
            "provider": "openai",
            "config": {
                "model": "gpt-4o-mini",
                "temperature": 0.0,
            }
        }
    }
}

m = Memory.from_config(config_dict=config)
```

```typescript TypeScript (Advanced)
const config = {
    llm: {
        provider: "openai",
        config: {
            model: "gpt-4o",
            temperature: 0.2,
            max_tokens: 2000,
        }
    },
    enableGraph: true,
    graphStore: {
        provider: "neo4j",
        config: {
            url: "neo4j+s://xxx",
            username: "neo4j",
            password: "xxx",
        },
        llm: {
            provider: "openai",
            config: {
                model: "gpt-4o-mini",
                temperature: 0.0,
            }
        }
    }
}

const memory = new Memory(config);
```
</CodeGroup>

<Note>
If you are using NodeSDK, you need to pass `enableGraph` as `true` in the `config` object.
</Note>

### Initialize Memgraph

Run Memgraph with Docker:

```bash
docker run -p 7687:7687 memgraph/memgraph-mage:latest --schema-info-enabled=True
```

The `--schema-info-enabled` flag is set to `True` for more performant schema
generation.

Additional information can be found on [Memgraph
documentation](https://memgraph.com/docs). 

User can also customize the LLM for Graph Memory from the [Supported LLM list](https://docs.mem0.ai/components/llms/overview) with three levels of configuration:

1. **Main Configuration**: If `llm` is set in the main config, it will be used for all graph operations.
2. **Graph Store Configuration**: If `llm` is set in the graph_store config, it will override the main config `llm` and be used specifically for graph operations.
3. **Default Configuration**: If no custom LLM is set, the default LLM (`gpt-4o-2024-08-06`) will be used for all graph operations.

Here's how you can do it:


<CodeGroup>
```python Python
from mem0 import Memory

config = {
    "graph_store": {
        "provider": "memgraph",
        "config": {
            "url": "bolt://localhost:7687",
            "username": "memgraph",
            "password": "xxx",
        },
    },
}

m = Memory.from_config(config_dict=config)
```

```python Python (Advanced)
config = {
    "embedder": {
        "provider": "openai",
        "config": {"model": "text-embedding-3-large", "embedding_dims": 1536},
    },
    "graph_store": {
        "provider": "memgraph",
        "config": {
            "url": "bolt://localhost:7687",
            "username": "memgraph",
            "password": "xxx"
        }
    }
}

m = Memory.from_config(config_dict=config)
```
</CodeGroup>

## Graph Operations
The Mem0's graph supports the following operations:

### Add Memories

<Note>
Mem0 with Graph Memory supports both `user_id` and `agent_id` parameters. You can use either or both to organize your memories. Use `userId` and `agentId` in NodeSDK.
</Note>

<CodeGroup>
```python Python
# Using only user_id
m.add("I like pizza", user_id="alice")

# Using both user_id and agent_id
m.add("I like pizza", user_id="alice", agent_id="food-assistant")
```

```typescript TypeScript
// Using only userId
memory.add("I like pizza", { userId: "alice" });

// Using both userId and agentId
memory.add("I like pizza", { userId: "alice", agentId: "food-assistant" });
```

```json Output
{'message': 'ok'}
```
</CodeGroup>


### Get all memories

<CodeGroup>
```python Python
# Get all memories for a user
m.get_all(user_id="alice")

# Get all memories for a specific agent belonging to a user
m.get_all(user_id="alice", agent_id="food-assistant")
```

```typescript TypeScript
// Get all memories for a user
memory.getAll({ userId: "alice" });

// Get all memories for a specific agent belonging to a user
memory.getAll({ userId: "alice", agentId: "food-assistant" });
```

```json Output
{
    'memories': [
        {
            'id': 'de69f426-0350-4101-9d0e-5055e34976a5',

        }
    ]
}
```
</CodeGroup>


### Delete all Memories

<CodeGroup>
```python Python
# Delete all memories for a user
m.delete_all(user_id="alice")

# Delete all memories for a specific agent belonging to a user
m.delete_all(user_id="alice", agent_id="food-assistant")
```

```typescript TypeScript
// Delete all memories for a user
memory.deleteAll({ userId: "alice" });

// Delete all memories for a specific agent belonging to a user
memory.deleteAll({ userId: "alice", agentId: "food-assistant" });
```
</CodeGroup>

# Example Usage
Here's an example of how to use Mem0's graph operations:

1. First, we'll add some memories for a user named Alice.
2. Then, we'll visualize how the graph evolves as we add more memories.
3. You'll see how entities and relationships are automatically extracted and connected in the graph.

### Add Memories

> **Note:** The Graph Memory implementation is not standalone. You will be adding/retrieving memories to the vector store and the graph store simultaneously.

## Using Multiple Agents with Graph Memory

When working with multiple agents, you can use the `agent_id` parameter to organize memories by both user and agent. This allows you to:

1. Create agent-specific knowledge graphs
2. Share common knowledge between agents
3. Isolate sensitive or specialized information to specific agents

### Example: Multi-Agent Setup

<CodeGroup>
```python Python
# Add memories for different agents
m.add("I prefer Italian cuisine", user_id="bob", agent_id="food-assistant")
m.add("I'm allergic to peanuts", user_id="bob", agent_id="health-assistant")
m.add("I live in Seattle", user_id="bob")  # Shared across all agents

# Search within specific agent context
food_preferences = m.search("What food do I like?", user_id="bob", agent_id="food-assistant")
health_info = m.search("What are my allergies?", user_id="bob", agent_id="health-assistant")
location = m.search("Where do I live?", user_id="bob")  # Searches across all agents
```

```typescript TypeScript
// Add memories for different agents
memory.add("I prefer Italian cuisine", { userId: "bob", agentId: "food-assistant" });
memory.add("I'm allergic to peanuts", { userId: "bob", agentId: "health-assistant" });
memory.add("I live in Seattle", { userId: "bob" });  // Shared across all agents

// Search within specific agent context
const foodPreferences = memory.search("What food do I like?", { userId: "bob", agentId: "food-assistant" });
const healthInfo = memory.search("What are my allergies?", { userId: "bob", agentId: "health-assistant" });
const location = memory.search("Where do I live?", { userId: "bob" });  // Searches across all agents
```
